TIME GAS-LIGHTING MECHANISM.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed January 8, 1906. Serial No. 295.081.

To all whom, it nuty concern:

Be it known that I, New FRED ENGLUND, a citizen of the United States, and a resident of Ashland, in the county of Ashland and State of Wisconsin, have invented a new and Improved Time Gas-Lighting Mechanism, of which the following is a full, clear, and exact description.

The object of the invention is to provide means for automatically starting or stopping the operation of a lamp at any predetermined time.

The invention is particularly adapted to use in connection with gas-lamps which are controlled by opening or closing the gas-supply. In its preferred embodiment, which is here shown, it is employed as a means for automatically extinguishing a gas-lamp at any desired hour.

The invention resides in certain special features of construction and combinations of parts, which will be fully set forth hereinafter, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, which illustrate as an example the preferred embodiment of myinvention, in which drawings Figure 1 is a side view of the invention. Fig. 2 is a detail of the device connected with a gaslamp, the view showing the part of the gas-lamp or burner in section. Fig. 3 is a bottom view of the parts shown in Fig. 2, and Fig. 4 is a detail view showing the clock attachment.

10 indicates the stem of the valve controlling the gas-supply to the lamp 11. This lamp may be of any desired form. As here shown, it is of the type using a plurality of burners within an inclosing globe and commonly designated gas arc-light. To the lower end of the stem 11 a link 12 is joined, and to the lower end of this link an arm 14 is in turn fastened, the arm projecting horizontally from the link.

15 indicates a bracket which depends from the globe-holder to any convenient part of the lamp and has fastened to its lower end a horizontal arm 16, mounting a pulley 17. The arm 16, as shown best in Fig. 3, extends at right angles to the arm 14-, and over the pulley 17 is rove a cord 18, which has one end attached to the end of the arm 14.

The clock, as shown in Figs. 1 and 4, is preferably of the well-known alarm type and has a drum 19 connected to the lower end of the alarm-spring, so that by setting the clock at the hour at which it is desired to extinguish the light said drum 19 will rotate, and the second end of the cord 18 is wound over the drum, the rotation of the drum thus exerting a tension on the cord and causing the parts 10 and 12 to be turned, thus cutting off the gas-supply and extinguishingthe light.

The cord 18 may be guided by guide devices located in various positions, according to the surroundings. As here shown, the cord passes from the pulley 17 to a pulley 20, fastened to the ceiling of the apartment in which the lamp 11 is located, and from this pulley the cord passes down to a pulleyZl, attached, for example, to the wall back of the clock.

In the use of the invention the parts are adjusted as shown in Fig. 1 and the clock is set at the hour at which it is desired to extinguish the lamp. As the alarm of the clock rings the drum 19 will turn and wind the cord 18, thus exerting a swinging force on the arm 14 and turning the stem 10 to shut off the gassupply. It is obvious that the arrangement may be reversed in connection with a gaslamp using a pilot-flame, so as to automatically light the lamp at any stated hour or to control other lamps than those using a gaseous fuel.

Having thus described the preferred form of my invention, what I claim as new, and de sire to secure by Letters Patent, is

1. The combination with a lamp, its valvestem, an alarm-clock, and a drum operated by the alarm-clock, of a right-angled bracket having the end of one member secured to the lamp with its other member extending horizontally outwardly and provided with a guide-pulley at its end, a right-angled arm having one member secured to the lower end of the valve-stem with its other member extending horizontally and normally at right angles to the horizontal member of the bracket, upper and lower guide-pulleys, and a cord passing around the said guide-pulleys and having one end secured to the horizontal member of the said arm and its other end secured to the drum, substantially as herein shown and described.

2. The combination with an alarm-clock, a lamp and its valve-stem provided with an arm projecting at right angles therefrom, of a right-angled bracket having the end of one member secured to the lamp and its other member extending horizontally and out- Wardly and provided at its end With a guide- I In testimony whereof I have signed my pulley, the arm of the valve-stern normally name to this specification in the presence of 10 extending at right angles to the horizontal two subscribing Witnesses.

member of the bracket, and an operatingcord having one end secured to the arm of the NELS FRED ENGLUND' valve-stem, passed around the guide-pulley of Witnesses: the bracket and its other end connected with GRACE MERRILL,

a movable member of the clock. GEO. F. MERRILL.
